Answers to big questions could lie in small particles

Scientists planning the next decade in US particle physics consider what we can learn from fundamental particles called neutrinos. We live in a galaxy permeated with tiny particles called neutrinos. Trillions of them stream through each of us each second. They are everywhere, but much remains a mystery about these particles, which could be key to understanding our universe. During the first weekend of November, a couple of hundred scientists gathered at Fermilab to discuss ways to unravel the my...
